Receiving Position Requests

You can configure the radio to reply automatically to incoming position requests, or prompt you to review and
approve the incoming requests before replying
When you receive a position request with automatic position replies enabled, SENDING ACKNOWLEDGE
appears on the screen, and the radio sends your position automatically. After the position successfully
transmits, POSITION SENT appears on the screen.
When you receive a position request with automatic position replies disabled, POS. REQUEST appears on the
screen.
When you receive a position request with automatic position replies disabled, select OK, and select an
option:
• To reply to the position request with your current position, select OK.
If GPS-position or manual-position data is available, the radio transmits your position to the other vessel.
• To ignore the position request, press CLEAR.

Receiving Position Calls

When you receive a position call, POS. SEND and the position data appear on the screen.
Select OK.
The radio saves the position report in the call log.

Receiving Group Calls

requested channel. If the channel requested is invalid, INVALID CH REQUEST appears on the screen.

Position Tracking
